Like anything else, it's only simple if you know how to do it. I worked as a pump rebuilder - but son is not experienced. 1/6 of a turn of the pump head screw is probably all he needs to pass - but I'm not in Colorado.
The IDI pre-Powerstroke Fords with 6.9s or 7.3 International Harvester engines use the same Roosamaster/Stanadyne DB2 pumps as the 6.2 and 6.5 GM diesels (up to 93). I've got versions of all of them. My newest IDI is my early 94 F250 - the last 7.3 IDI turbo they made before changing to DI Powerstroke in late 94.

By using a heavy kerosene mix, it seems the effect would be the same as turning the fuel-delivery down. The injection pump meters fuel by volume. By volume, there is less "fuel" in kerosene than there is with #2 diesel. #2 Diesel fuel at 60 degrees F weighs 820-950 kg. per cub. meter. Kerosene at 60 degrees F weights 817 kg. per cub. meter. Gasoline at 60 degrees F weighs 737.22 kg. per cub. meter

We thought we could get by with this since the engine ran perfectly and would not need any internal work. After the cleanup and painting was done, we began reassembly and finally came to t
